Sansevieria plant named ‘OSV Sans 017’

ABSTRACT

A new and distinct Sansevieria plant having dark green and light grey horizontally striped leaves with a thin cream border.

Botanical classification: Sansevieria sp.

Varietal denomination: ‘OSV Sans 017’.

BACKGROUND OF THE INVENTION

The present invention comprises a new and distinct variety ofSansevieria plant, having the varietal name of ‘OSV Sans 017’ andcommercially referred to as “Twilight Star”. The new variety wasdiscovered and selected by the breeder in a cultivated production bedenvironment in Williamsburg, Costa Rica as a naturally occurringmutation amongst a population of unpatented and unnamed Sansevieriaplants. As such, the exact parentage is unknown. The new variety wasselected and first asexually reproduced by rhizome cuttings inWilliamsburg, Costa Rica. ‘OSV Sans 017’ has been trial and field testedand has been found to retain its distinctive characteristics and remaintrue to type through successive propagations. The present invention hasnot been evaluated under all possible environmental conditions. Thephenotype may vary with variations in environment without a change inthe genotype of the plant.

When compared to Sansevieria variety named ‘OSV Sans 004’ (U.S. Plantpatent application Ser. No. 17/495,477), the new variety exhibits asimilar rosette leaf formation with leaves having horizontally stackedlines and a gladiate leaf shape. However, ‘OSV Sans 017’ differs from‘OSV Sans 004’ in having longer leaves with very thin, cream coloredmargins. Further, the following characteristics distinguish ‘OSV Sans017’ from other Sansevieria varieties known to the breeder:

-   -   Rosette leaf formation;    -   Very thin, cream colored margins; and    -   Horizontally stacked and static lines are present across leaves.

DESCRIPTION OF THE DRAWING

The accompanying photographic drawing taken at approximately 18 weeks ofage illustrates the new variety, with the colors being as nearly true asis possible with color illustrations of this type.

DESCRIPTION OF THE PLANT

The following detailed description sets forth the characteristics of thenew variety at approximately 2 years of age. The data which definesthese characteristics was collected in a greenhouse in September of 2021in Winter Garden, Fla. Plants of the new variety were grown under 2,000foot candles of artificial light in 15 cm pots in a climate-controlledgreenhouse in Winter Garden, Fla. having 86% relative humidity and anaverage temperature of 28° C. Color references are primarily to theMunsell Plant Tissue Color Book, 2019 publication, except where generalcolor terms are used.
